Bernt E. Uhlin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Adhesin antigens, antibodies and DNA fragment encoding the antigen, methods and means for diagnosis and immunization etc.
    Patent number: 4795803
    Abstract: An antigen which, as its major immunizing component, comprises a determinant of an adhesin polypeptide or an immunogenically active subsequence thereof or a precursor therefor which is convertible to an immunogenically active form, antibodies against which determinant react with the adhesion polypeptide produced by pathogenic adhesin-forming bacteria which adhere to mammalian tissue, antibodies against such antigen, and DNA expressing, as a principal gene product thereof, such antigen.
    Type: Grant
    Filed: February 19, 1986
    Date of Patent: January 3, 1989
    Assignee: Syn-Tek AB
    Inventors: Frederick C. Lindberg, Bjorn O. Lund, Britt M. Baga, Mari E. Norgren, Mikael Goransson, Bernt E. Uhlin, Jan S. Normark, David L. Lark
  • Bacteria carrying plasmid having temperature dependent plasmid copy number
    Patent number: 4499189
    Abstract: Gene products of plasmid DNA, such as proteins, are prepared in high yields by cultivating bacteria carrying a plasmid which shows a controlled constant plasmid copy number at one temperature and a much higher or totally uncontrolled copy number at a different temperature. The plasmid may be prepared by recombinant DNA technique using a cloning vector showing the temperature dependent plasmid copy number pattern.
    Type: Grant

    Date of Patent: February 12, 1985
    Assignee: A/S Alfred Benzon
    Inventors: Bernt E. Uhlin, Kurt Nordstrom, Soeren Molin
